1. _ ENET Federal Communications Commission Office of Engineering and Technology Laboratory Division October 31 2013 Equipment Authorization Guidance for Hearing Aid Compatibility Introduction 1 This publication provides guidance to clarify the Hearing Aid Compatibility HAC equipment certification requirements for wireless handsets subject to Section 20 19 of the FCC rules 2 Wireless handsets that provide Commercial Mobile Radio Service CMRS telephone service using air interfaces and frequency bands for which technical standards are defined in ANSI C63 19 2007 and ANSI C63 19 2011 are subject to Section 20 19 3 Manufacturers of wireless handsets that are seeking certification of a handset as hearing aid compatible under Section 20 19 must submit as part of the equipment certification process a test report that demonstrates HAC compliance Testing must be performed exclusively under either ANSI C63 19 2007 or ANSI C63 19 2011 as appropriate It is not permitted to perform some of the tests on a handset under one edition and remainder with another edition of the standard 4 Handsets subject to Section 20 19 are tested using either ANSI C63 19 2007 or ANSI C63 19 2011 under the following conditions The term handset as used in this document refers to a handheld device granted under a specific FCC ID and not to multiple model variations marketed under one FCC ID This document will note when a new distin2. 19 requirements Testing must be done in accordance with ANSI C63 19 under the worst case operating mode highest interference potential No external special parts or ancillary devices are permitted in order to demonstrate HAC compliance Handset models with user instructions that disable any of its features degrade performance reduce RF output power degrade battery performance etc for the purpose of meeting HAC compliance are not permitted However power reduction is permitted for the GSM air interface in the 1900 MHz Band for certain manufacturers of handsets using a user selectable mode of reducing the power by no more than 2 5 dB under the provisions of Section 20 19 c 1 Handsets using this provision must be noted in the test report and provide the appropriate text in the grant comment field and disclosure statements 1l Any type of equipment modification antenna position design metallic surface adding system processes changing battery capacity or type etc has the potential to change the rating The manufacturer must evaluate the equipment modification to determine if there is a change in the rating and if a Class II permissive change is required Equipment changes that do not result in a change of the HAC rating being marketed and reported to the WTB do not require a Class II permissive change Form 731 application and can be considered a Class I permissive change Permissive Change Policies KDB 178919 Appendix A 2850
3. changes that affect the HAC rating must be reported as a Class II permissive change The handset must be given a new model designation distinct from that of the prior version of the handset A Class II permissive change application that only includes an M rating report for a handset previously granted with a rating of M T is only acceptable if 1 the handset is no longer to be marketed or reported with a rating of M T as a distinctive new model or 2 as a distinctive new model The grant comment associated with the Class II permissive change would then be HAC Ratings M T M for examples 1 and 2 respectively When adding a T coil rating for a device according to the Class II permissive change procedures for handsets a complete M report and a complete T report must be submitted with the Form 731 application Only if there has been no product change to add the T coil or the T coil is at the same location as the acoustical output location see clause 5 5 of ANSI C63 19 2011 then the previously filed report can be resubmitted If the manufacturer builds the product with alternative components it must be tested to show compliance using the components representing the worst case situation according to the guidance for the permissive change procedure 5 Features to be Tested 31 32 33 34 HAC Test environments probes equipment test fixtures etc must be properly calibrated according to the manufacturer and ANSI C63
4. marketed and reported as an M or one complete M report and one complete T report see example in appendix A for a model marketed and reported as M T 9 Any handset supporting CMRS service that is designed to be held to the ear is considered a handset under Section 20 19 This includes any handset even if the manufacturer claims that usually or most often users will operate it in a speakerphone mode or other mode If a device cannot be practically held to the ear for voice communication it is not subject to the HAC requirements of Section 20 19 This includes devices that provide voice communication only through a speakerphone headset or other method or accessory 10 Concurrent connections or services are modes that permit active voice calls at the same time with other active connections for data or other voice calls For the purpose of this document concurrent connections are defined into two categories 1 Concurrent connections using simultaneous transmissions and 2 Concurrent connections using other modes not using simultaneous transmissions a Handsets that that have the ability to support concurrent connections using simultaneous transmissions shall be independently tested for each air interface band Concurrent simultaneous transmissions defined for this document means transmitters that are radiating simultaneously establishing independent concurrent connections operating over separate or the sa

C ID HAC Rating standard version in the Equipment Authorization System EAS There is no requirement that the grant of certification and HAC report exhibits include an up to date model designation in the EAS for each model reported to the WTB 285076 DO1 HAC Guidance v04 1 a Handsets that have modes and band s limited to those defined within ANSI C63 19 2007 may use either ANSI C63 19 2007 or ANSI C63 19 2011 b Handsets that have modes and band s defined within ANSI C63 19 2011 i e not addressed in ANSI C63 19 2007 can only use ANSI C63 19 2011 to demonstrate compliance 5 Voice over IP transport for CMRS over network interfaces included in C63 19 2011 need to be tested or addressed for HAC compliance See companion attachment 285076 D02 T Coil testing for CMRS IP to this KDB 285076 for further guidance and exemptions 6 Handsets that only operate in bands that are not addressed in ANSI C63 19 2007 or ANSI C63 19 2011 are not subject to Section 20 19 HAC requirements Equipment Certification Filing Requirements 7 The HAC test report exhibit must be submitted with a Form 731 application for equipment authorization either as an original application or as a Class II Permissive Change application to add or change the HAC rating of a handset subject to Section 20 19 8 A Form 731 application associated with a HAC tested handset must include a test report exhibit s which contains one complete M test report for each model
